I have not found a 400 ex who can beat me yet. so goin 130 and 180? its not ganna happin. you guys are idiots. the 700 raptor wont even do that stock and you guys wont touch one of those in your life time. The honda 450 and yfz 450 wont even do that stock and you think you can do that on a 400 stock. the 450s cant even do that with modified. so quit lien. its not ganna happin in a million years.
